Seafields Solutions works to catch and grow Sargassum, a seaweed that naturally captures CO2 as it grows, photosynthesises and sinks to the seafloor.
Their ‘Catch and Grow’ farms, located near shore, enable them to provide a consistent feedstock of seaweed for industry, while enhancing the natural process of large scale CO2 sequestration from the atmosphere.
They will scale up their Catch and Grow farms into large, open-ocean Sargassum paddocks, which will grow modularly until reaching a scale allowing removal of a billion tons of CO2 from the atmosphere each year.
Sargassum is a valuable feedstock for industry and can be converted into a range of products including bioplastic, biofertiliser and biofuels.
Any Sargassum not sold to industry will be shredded and baled, “locking away CO2 for millenia.”
The bales will be deposited at selected sites on the deep-sea floor at roughly 3000-5000 metres to lock away the CO2.
